Sažetak

Nuclear waste repositories should be designed in order to mantain the waste for several thousand years. Although the waste is stored in tanks that can persist the most extreme conditions, it is necessary to ensure that gases that can come into existence nearby the storage tank will not spread far from the repository well. Technology that was developed by petroleum exploration and production industry is at sofisticated enough to determine all geological and petrophysical aspects of the waste disposal. The main task is to determine if there is possibility of leakage pathways in the repository rock. That requires exploration in order to define geological model, by utilisation of well logging, 3D and 4D seismic measurements. Petrophysical measurements give data required for well-log calibration and input data for reservoir flow calculations and simulations. Well testing of pressure changes can give validation of lab data, and can be use din order to correct input data for flow calculations. Because of semi-empirical nature of the measured data interpretation, some testing and calculation methods should be slightly modified for nuclear waste repository.
